We would only see a brief reduction of the trend towards an increase in the number of infected subjects in late October (26 October 2020), before again experiencing an exponential rise in cases. With regard to groups H and U, the two-week restrictions measure would not be able to generate a trough capable of reducing hospital pressure, and a peak of 1946 (20 February 2021) and 310 (25 February 2021) cases, respectively, would appear. This volume would greatly exceed the number of patients admitted to hospital and to the ICU seen in the past period of March to April 2020 (<a class="elsevierStyleCrossRef" href="#fig0015">Fig. 3</a>).

However, we would find a high prevalence peak of 50,485 cases at a later date with respect to the peak estimated for the previous scenario (2 March 2021).
